Health Watch - The Brain: Short-term Memory
Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.
This week on Health Watch, we’re talking about how the brain works. It takes minutes to hours for the brain to store permanent memories. Researchers at UT Southwestern Medical Center have learned how the brain buffers rapidly incoming information by holding it temporarily.
Individual nerve cells in the front of the brain — the most highly evolved area — can hold memories for as long as a minute. Dr. Don Cooper, a UT Southwestern psychiatrist, says it’s like the difference between random-access memory, or RAM, on a computer and saving information to a disk. RAM is temporary and rewritable, while information on a disk can be accessed over and over again. The temporary memory is susceptible to distraction and is easily disrupted. This research could be helpful in understanding addiction, attention disorders and stress-related memory loss. In the long term, researchers hope to develop drugs that can help maintain memory or resist addiction.
